Problems solved by technology
[0004] In view of the above-mentioned related technical solutions, the inventors found that: the lost foam casting production line lacks a treatment process for harmful gases. During the process of replacing the molten metal with the model, the model will gasify and form a large amount of harmful gas, which will cause serious damage to the factory environment. pollution, and affect the health of workers

This application relates to the technical field of lost foam casting, in particular to an aluminum alloy lost foam casting system. The box sleeve is set on the sand box; the bottom of the sand box is provided with a plurality of exhaust holes, and the bottom surface inside the gas collection box is provided with a plurality of suction holes corresponding to the exhaust holes one by one. The wall of the gas collection box is connected to the inside; the wall of the gas collection box is provided with an air extraction hopper that communicates with the interior of the box wall of the gas collection box, and the port of the air extraction hopper near the gas collection box is provided with activated carbon; the end of the air extraction hopper away from the gas collection box is connected There is a negative pressure fan; the bottom of the sand box is laid with a sand barrier, and the sand barrier is made of high temperature resistant and breathable material; it can reduce the harmful gas formed by the gasification of the model and directly enter the atmosphere without treatment, thereby reducing the impact on the environment. The purpose of reducing the pollution of the atmospheric environment and reducing the adverse effects on the health of workers.
Description
technical field [0001] The present application relates to the technical field of lost foam casting, and in particular, to an aluminum alloy lost foam casting system. Background technique [0002] Lost foam casting, also known as dry sand solid negative pressure casting, is one of the most advanced casting processes in the world. In this method, a foam model is first made according to the process requirements, coated with special high temperature resistant paint, and then placed in the mold after drying. In the special sand box, the molding sand is filled according to the process requirements and vibrated and compacted. After that, the molten metal is poured into the sand box to make the model vaporize and disappear. The molten metal replaces the model and reproduces the same casting as the foam model. [0003] An aluminum alloy lost foam casting production line disclosed by the Chinese invention patent with the authorization announcement number of CN106513658B, includes an a...
